Thank you. May you please allow me to sum your prescriptions up?
1. If a number that is less than 11 is an exact count, it must be spelled out.
2. If a number is just an approximation, it must be modified by a qualifier.
3. Use figures--less than 11 or not--before a unit of measure, statistical formula, mathematical function, and those that represent age, time, money, size, score, and points on scale.
